Description

Technical Field

[0001] This application relates to the field of server rack technology, and more specifically, to a server rack and data center with a dual cooling source system. Background Technology

[0002] In this era of rapid information technology development, data centers, as the core hubs for information storage and processing, play a crucial role in ensuring the secure and stable operation of businesses. Among these, the cooling system is a vital cornerstone for guaranteeing the secure and stable operation of a data center. When the data center's cooling system fails or is anticipated to be unable to continue providing cooling, the continuous operation of one or more core devices will be affected, leading to data backup failures or business migration disruptions, thus impacting the normal operation of the data center. Utility Model Content

[0003] This application provides a server rack and data center with a dual cooling source system. The server rack has two cooling modes to facilitate the normal operation of the server rack and ensure the normal operation of the data center.

[0004] This application is achieved through the following technical solution: In a first aspect, embodiments of this application provide a cabinet with a dual-cooling-source system, comprising a rack, a first movable enclosed box, and a second movable enclosed box. The rack includes a cabinet body and IT equipment and a rack-mounted air conditioner disposed within the cabinet body. The cabinet body has a first ventilation side and a second ventilation side disposed opposite to each other along a first direction, the first direction being perpendicular to the height direction of the cabinet body. The air outlet of the rack-mounted air conditioner faces the first ventilation side, and the air inlet of the rack-mounted air conditioner faces the second ventilation side. The first movable enclosed box is configured to be movably disposed on the first ventilation side, and the first movable enclosed box has an internally hollow structure. The second movable enclosed box is configured to be movably disposed on the second ventilation side, and the second movable enclosed box has an internally hollow structure. When the first movable enclosure is connected to the cabinet and closes the first ventilation side, and the second movable enclosure is connected to the cabinet and closes the second ventilation side, the first movable enclosure, the cabinet, and the second movable enclosure form a closed space. The first movable enclosure and the rack form a first cold air passage, and the second movable enclosure and the rack form a first hot air passage, so as to provide cooling circulation for IT equipment through rack-mounted air conditioning. When the first movable enclosure is separated from the cabinet and the second movable enclosure is separated from the cabinet, the rack-mounted air conditioning is turned off, and the cabinet provides cold air through an external cold source.

[0005] According to an embodiment of this application, a cabinet with a dual-cooling-source system has a first ventilation side and a second ventilation side arranged opposite to each other along a first direction. When an external cooling source provides cooling air, the cooling air can enter the cabinet through the first ventilation side to cool the IT equipment. After absorbing the heat from the IT equipment, the cooling air forms hot air, which can be discharged from the cabinet through the second ventilation side. The external cooling source and the cabinet form a cooling cycle. Furthermore, the cabinet of this application also includes a first movable enclosure and a second movable enclosure. The first movable enclosure has a hollow internal structure and a certain accommodating space. The second movable enclosure also has a hollow internal structure. The movable enclosure has a certain amount of storage space. Both the first and second movable enclosures are movable structures, used in conjunction with rack-mounted air conditioners. When the external cooling source fails or cannot meet the cooling requirements of the IT equipment, the first movable enclosure can be moved to the first ventilation side of the rack and sealed to the rack, while the second movable enclosure can be moved to the second ventilation side and sealed to the rack. The internal space of the first movable enclosure forms a first cold air channel with the rack, and the internal space of the second movable enclosure forms a first hot air channel with the rack. The rack-mounted air conditioner provides a cooling cycle for the IT equipment, achieving self-cooling of the rack. Therefore, the rack with a dual-cooling-source system mentioned in this application has two cooling modes: one using an external cooling source and the other using its own rack-mounted air conditioner. This allows for timely response to emergency failures, reduces the impact of temperature on IT equipment, facilitates the normal operation of IT equipment, and ensures the normal operation of the data center.

[0006] According to some embodiments of this application, a first movable enclosed box includes a first frame and a first enclosing plate. The first enclosing plate and the first frame cooperate to form a first cavity with one end open. The opening of the first cavity faces the cabinet. The first enclosing plate and the first frame are sealed together. When the first movable enclosed box is moved to be connected to the cabinet, the first frame is configured to be detachably connected to the cabinet and sealed together. The first opening of the cabinet on the first ventilation side communicates with the first cavity. A second movable enclosed box includes a second frame and a second enclosing plate. The second enclosing plate and the second frame cooperate to form a second cavity with one end open. The opening of the second cavity faces the cabinet. The second enclosing plate and the second frame are sealed together. When the second movable enclosed box is moved to be connected to the cabinet, the second frame is configured to be detachably connected to the cabinet and sealed together. The second opening of the cabinet on the second ventilation side communicates with the second cavity.

[0007] In the above scheme, the first sealing plate and the first frame cooperate to form a first cavity with one open end, so that the first movable sealing box has a large accommodating space. When the first movable sealing box is sealed to the cabinet, it is conducive to the flow of air in the first cold air channel formed by the first movable sealing box and the cabinet. The second sealing plate and the second frame cooperate to form a second cavity with one open end, so that the second movable sealing box has a large accommodating space. When the second movable sealing box is sealed to the cabinet, it is conducive to the flow of air in the first hot air channel formed by the second movable sealing box and the cabinet. For example, when the rack-mounted air conditioner provides a cooling cycle for IT equipment, the cold air delivered from the air outlet of the rack-mounted air conditioner enters the first cavity, circulates in the first cavity, and then enters the space where the IT equipment is located through the first opening. The cold air absorbs the heat of the IT equipment and forms hot air. The hot air is discharged from the cabinet through the second opening and enters the second cavity. The hot air circulates in the second cavity and then enters the rack-mounted air conditioner through the return air vent, forming a cold cycle. Meanwhile, the first movable enclosed box and the second movable enclosed box are detachably connected to the cabinet, which facilitates the assembly and disassembly of the first movable enclosed box and the cabinet, and the assembly and disassembly of the second movable enclosed box and the cabinet, in order to adapt to different refrigeration modes.

[0008] According to some embodiments of this application, the cabinet is provided with a plurality of first openings on the first ventilation side, the plurality of first openings being spaced apart along the height direction of the cabinet, and the plurality of first openings respectively corresponding to the air inlet side of the IT equipment and the air outlet of the rack-mounted air conditioner; the cabinet is provided with a plurality of second openings on the second ventilation side, the plurality of second openings being spaced apart along the height direction of the cabinet, and the plurality of first openings respectively corresponding to the air outlet side of the IT equipment and the air inlet of the rack-mounted air conditioner.

[0009] In the above scheme, the multiple first openings allow cold air to enter the space where the corresponding IT equipment is located, reducing the waste of cold air and facilitating the cooling of the IT equipment. Each second opening can be set up corresponding to a first opening to absorb the hot air from the IT equipment and exhaust it from the cabinet. When an external cold source provides cold air, the air outlet and return air inlet of the rack-mounted air conditioner are closed. Cold air enters the space where the IT equipment is located through the multiple first openings, facilitating the rapid cooling of the IT equipment. After absorbing the heat from the IT equipment, the cold air becomes hot air, which is exhausted from the cabinet through the multiple second openings, promoting air circulation. When the rack-mounted air conditioner provides cold circulation, the air outlet of the rack-mounted air conditioner sends out cold air. The cold air circulates within the first cavity and enters the space where the IT equipment is located through the multiple first openings, facilitating the rapid cooling of the IT equipment. After absorbing the heat from the IT equipment, the cold air becomes hot air, which is exhausted from the cabinet through the multiple second openings, promoting air circulation.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0031] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0035] In existing technologies, server racks typically only have one cooling mode. For example, a server rack uses a data center cooling source for cooling, with ventilation openings on the front and back. The data center cooling source provides cold air, which enters the rack from the front, absorbs heat from the IT equipment, and then exits as hot air from the back. Another example is a single-rack data center, which uses an internal cooling source, with air conditioning installed inside the rack, creating an internal circulation mode. However, these single-mode cooling solutions mean that when the data center cooling system malfunctions, IT equipment cannot function properly, leading to data backup failures or service migration disruptions, thus impacting the normal operation of the data center.

[0036] The structure of the cabinet with a dual cooling source system of this application will be described below with reference to the accompanying drawings.

[0037] Please refer to Figures 1 to 3 This application provides a cabinet 100 with a dual-cold source system, which includes a rack 10, a first movable enclosed box 20 and a second movable enclosed box 30.

[0038] The rack 10 includes a cabinet 11 and IT equipment 12 and rack-mounted air conditioner 13 disposed within the cabinet 11. The cabinet 11 has a first ventilation side P and a second ventilation side Q disposed opposite to each other along a first direction X. The first direction X is perpendicular to the height direction Z of the cabinet. The air outlet of the rack-mounted air conditioner 13 faces the first ventilation side P, and the air inlet of the rack-mounted air conditioner 13 faces the second ventilation side Q.

[0039] The cabinet 11 is rectangular and has a four-sided closed structure. It has openings that communicate with the interior only on the first ventilation side P and the second ventilation side Q, so that air can pass through the IT equipment 12 and so that cold air can enter the cabinet 11 to cool the IT equipment 12. For example, cold air enters the cabinet 11 through the opening on the first ventilation side P, absorbs the heat of the IT equipment 12 and forms hot air, and the hot air is discharged from the cabinet 11 through the opening on the second ventilation side Q.

[0040] In some embodiments, IT equipment 12 may include devices such as servers and switches.

[0041] In some embodiments, the rack-mounted air conditioner 13 may be positioned above, below, or in the middle of the IT equipment 12. Preferably, the rack-mounted air conditioner 13 is positioned below the IT equipment 12 to facilitate the arrangement of the IT equipment 12 above the rack-mounted air conditioner 13, while preventing condensate from the rack-mounted air conditioner 13 from dripping onto the IT equipment 12 and causing damage to the IT equipment 12.

[0042] The first movable enclosed box 20 is configured to be movably installed on the first ventilation side P. The first movable enclosed box 20 is a movable structure, which can be moved to the first ventilation side P according to usage needs and connected to the cabinet 11. The first movable enclosed box 20 has a hollow internal structure, that is, the first movable enclosed box 20 has a box-shaped structure, which can provide a large air flow space and facilitate air circulation.

[0043] The second movable enclosure 30 is configured to be movably installed on the second ventilation side Q. The second movable enclosure 30 is a movable structure, which can be moved to the second ventilation side Q according to usage requirements and connected to the cabinet 11. The second movable enclosure 30 has a hollow internal structure, that is, it is a box-shaped structure, providing a large airflow space and facilitating air circulation.

[0044] The cabinet has two cooling modes: one is to provide cooling circulation using the internal rack-mounted air conditioner 13, and the other is to provide cooling air from the computer room cold source.

[0045] For example, when the first movable enclosure 20 is connected to the cabinet 11 and closes the first ventilation side P, and the second movable enclosure 30 is connected to the cabinet 11 and closes the second ventilation side Q, the first movable enclosure 20, the cabinet 11, and the second movable enclosure 30 form a closed space. The first movable enclosure 20 and the rack 10 form a first cold air passage, and the second movable enclosure 30 and the rack 10 form a first hot air passage, so as to provide cooling circulation for the IT equipment 12 through the rack-mounted air conditioner 13. In this cooling mode, the air outlet of the rack-mounted air conditioner 13 delivers cold air, which flows in the first cold air passage and enters the cabinet 11 through the opening of the first ventilation side P of the cabinet 11. The cold air absorbs the heat of the IT equipment 12 to form hot air. The hot air leaves the cabinet 11 from the opening of the second ventilation side Q of the cabinet 11, enters the first hot air passage, and then enters the return air vent of the rack-mounted air conditioner 13, thereby completing the air circulation.

[0046] For example, when the first movable enclosed box 20 is separated from the cabinet 11 and the second movable enclosed box 30 is separated from the cabinet 11, the rack-mounted air conditioner 13 is turned off, and the cabinet 11 provides cooling air through an external cold source.

[0047] According to an embodiment of this application, a cabinet 100 with a dual-cold-source system has a cabinet 11 having a first ventilation side P and a second ventilation side Q arranged opposite to each other along a first direction X. When an external cold source provides cold air, the cold air can enter the cabinet 11 through the first ventilation side P to cool the IT equipment 12. After absorbing the heat from the IT equipment 12, the cold air forms hot air, which can be discharged from the cabinet 11 through the second ventilation side Q. The external cold source and the cabinet 11 form a refrigeration cycle. Furthermore, the cabinet of this application also includes a first movable enclosed box 20 and a second movable enclosed box 30. The first movable enclosed box 20 has a hollow internal structure and a certain accommodating space. The second movable enclosed box 30 also has a hollow internal structure. The movable enclosure 30 has a certain amount of storage space. Both the first movable enclosure 20 and the second movable enclosure 30 are movable structures. Used in conjunction with the rack-mounted air conditioner 13, when the external cooling source fails or cannot meet the cooling requirements of the IT equipment 12, the first movable enclosure 20 can be moved to the first ventilation side P of the cabinet and sealed to the cabinet, and the second movable enclosure 30 can be moved to the second ventilation side Q of the cabinet and sealed to the cabinet. The internal space of the first movable enclosure 20 forms a first cold air channel with the cabinet 11, and the internal space of the second movable enclosure 30 forms a first hot air channel with the cabinet 11. The rack-mounted air conditioner 13 provides a cooling cycle for the IT equipment 12, achieving self-cooling of the cabinet. Therefore, the cabinet 100 with a dual cooling source system mentioned in this application has two cooling modes: one using an external cooling source and the other using its own rack-mounted air conditioner 13. This allows for timely response to emergency failures, reduces the impact of temperature on the IT equipment 12, facilitates the normal operation of the IT equipment 12, and ensures the normal operation of the data center.

[0048] Please refer to Figure 1 and Figure 3 According to some embodiments of this application, the first movable enclosed box 20 includes a first frame 21 and a first enclosed plate 22. The first enclosed plate 22 and the first frame 21 cooperate to form a first cavity 23 with one end open. The opening of the first cavity 23 is set towards the cabinet 11. The first enclosed plate 22 and the first frame 21 are sealed together.

[0049] The first sealing plate 22 is disposed on multiple sides of the first frame 21, such that the structure after the first sealing plate 22 and the first frame 21 are assembled forms a first cavity 23 with one end open. There can be multiple first sealing plates 22, and multiple first sealing plates 22 are disposed on multiple sides of the first frame 21, so that only one side of the first frame 21 is not provided with a first sealing plate 22.

[0050] When the first movable enclosed box 20 moves to connect with the cabinet 11, the first frame 21 is configured to be detachably connected to the cabinet 11 and sealed to the cabinet 11. The first opening 111 on the first ventilation side P of the cabinet 11 communicates with the first cavity 23. For example, after the first sealing plate 22 is engaged with the first frame 21, one side of the first frame 21 is not provided with the first sealing plate 22, forming an opening in the first cavity 23. When the first movable enclosed box 20 moves to connect with the cabinet 11, the opening of the first cavity 23 corresponds to the first opening 111 on the first ventilation side P of the cabinet 11, so that the first cavity 23 communicates with the interior of the cabinet 11, forming a first cold air channel.

[0051] According to some embodiments of this application, the second movable enclosed box 30 includes a second frame 31 and a second enclosed plate 32. The second enclosed plate 32 and the second frame 31 cooperate to form a second cavity 33 with one end open. The opening of the second cavity 33 is disposed facing the cabinet 11. The second enclosed plate 32 and the second frame 31 are sealed together.

[0052] The second sealing plate 32 is disposed on multiple sides of the second frame 31, such that the structure after the second sealing plate 32 and the second frame 31 are assembled forms a second cavity 33 with one end open. There can be multiple second sealing plates 32, which are disposed on multiple sides of the second frame 31, so that only one side of the second frame 31 is not provided with a second sealing plate 32.

[0053] When the second movable enclosure 30 moves to connect with the cabinet 11, the second frame 31 is configured to be detachably connected to the cabinet 11 and sealed to the cabinet 11. The second opening 112 of the cabinet 11 on the second ventilation side Q communicates with the second cavity 33. For example, after the second sealing plate 32 is engaged with the second frame 31, one side of the second frame 31 is not provided with the second sealing plate 32, forming an opening in the second cavity 33. When the second movable enclosure 30 moves to connect with the cabinet 11, the opening of the second cavity 33 corresponds to the second opening 112 of the second ventilation side Q of the cabinet 11, so that the second cavity 33 communicates with the interior of the cabinet 11, forming a first hot air channel.

[0054] In the above scheme, the first sealing plate 22 and the first frame 21 cooperate to form a first cavity 23 with one open end, giving the first movable sealing box 20 a larger capacity. When the first movable sealing box 20 is sealed to the cabinet 11, it facilitates the flow of air within the first cold air channel formed by the first movable sealing box 20 and the cabinet 11. The second sealing plate 32 and the second frame 31 cooperate to form a second cavity 33 with one open end, giving the second movable sealing box 30 a larger capacity. When the second movable sealing box 30 is sealed to the cabinet 11, it facilitates the flow of air within the first hot air channel formed by the second movable sealing box 30 and the cabinet 11. For example, when the rack-mounted air conditioner 13 provides a cooling cycle for the IT equipment 12, the cold air delivered from the air outlet of the rack-mounted air conditioner 13 enters the first cavity 23. The cold air circulates within the first cavity 23 and then enters the space where the IT equipment 12 is located through the first opening 111. The cold air absorbs the heat from the IT equipment 12 and forms hot air. The hot air is discharged from the cabinet 11 through the second opening 112 and enters the second cavity 33. The hot air circulates within the second cavity 33 and then enters the rack-mounted air conditioner 13 through the return air vent, forming a cold cycle. Simultaneously, the first movable enclosed box 20 and the second movable enclosed box 30 are detachably connected to the cabinet 11, facilitating the assembly and disassembly of the first movable enclosed box 20 and the cabinet 11, and the second movable enclosed box 30 and the cabinet 11, to adapt to different cooling modes.

[0055] Please refer to Figure 1 and Figure 3 According to some embodiments of this application, the cabinet 11 is provided with a plurality of first openings 111 on the first ventilation side P. The plurality of first openings 111 are spaced apart along the height direction Z of the cabinet. The plurality of first openings 111 correspond to the air inlet side of the IT equipment 12 and the air outlet of the rack-mounted air conditioner 13, respectively.

[0056] In some embodiments, the cabinet 11 may be provided with a plurality of first baffles 113 on the first ventilation side P. The plurality of first baffles 113 are spaced apart along the height direction Z of the cabinet. Each first baffle 113 is sealed to the inner surface of the cabinet 11, and a first opening 111 is formed between two adjacent first baffles 113. Cold air can only enter the interior of the cabinet 11 through the first opening 111. The IT equipment 12 may be set corresponding to the first opening 111 so that the cold air entering through the first opening 111 can cool the IT equipment 12. The air outlet of the rack-mounted air conditioner 13 may be set corresponding to the first opening 111 so that the cold air delivered from the air outlet of the rack-mounted air conditioner 13 can enter the first cavity 23, which is conducive to the circulation of cold air. When the cabinet uses an external cold source to provide cold air, the cold air provided by the external cold source can also cool the rack-mounted air conditioner 13 through the first opening 111.

[0057] According to some embodiments of this application, the cabinet 11 is provided with a plurality of second openings 112 on the second ventilation side Q. The plurality of second openings 112 are spaced apart along the height direction Z of the cabinet, and the plurality of first openings 111 correspond to the air outlet side of the IT equipment 12 and the air inlet of the rack-mounted air conditioner 13, respectively.

[0058] In some embodiments, the cabinet 11 may be provided with a plurality of second baffles 114 on the second ventilation side Q. The plurality of second baffles 114 are spaced apart along the height direction Z of the cabinet. Each second baffle 114 is sealed to the inner surface of the cabinet 11, and a second opening 112 is formed between two adjacent second baffles 114. Hot air can only leave the cabinet 11 through the second opening 112. The IT equipment 12 may be provided corresponding to the second opening 112. After the cold air exchanges heat with the IT equipment 12 and absorbs the heat of the IT equipment 12 to form hot air, the hot air leaves the cabinet 11 through the second opening 112, reducing the residence time of the hot air inside the cabinet 11. The air inlet of the rack-mounted air conditioner may be provided corresponding to the second opening 112. On the one hand, when the rack-mounted air conditioner provides cooling circulation for the cabinet 11, it is beneficial for the hot air to return to the return air inlet of the rack-mounted air conditioner 13 through the second opening 112. On the other hand, when an external cold source provides cold air, it is beneficial for the hot air that has absorbed the temperature of the rack-mounted air conditioner to leave the cabinet 11.

[0059] In the above scheme, the arrangement of multiple first openings 111 allows cold air to enter the space where the corresponding IT equipment 12 is located, reducing the waste of cold air and facilitating the cooling of the IT equipment 12. Each second opening 112 can be configured corresponding to a first opening 111 to absorb the hot air from the IT equipment 12 and exhaust it from the cabinet 11. When an external cold source provides cooling, the air outlet and return air inlet of the rack-mounted air conditioner 13 are closed, and cold air enters the space where the IT equipment 12 is located through the multiple first openings 111, facilitating the rapid cooling of the IT equipment 12. After absorbing the heat from the IT equipment 12, the air becomes hot air. The hot air is discharged from the cabinet 11 through multiple second openings 112, which facilitates air circulation. When the rack-mounted air conditioner 13 provides cold circulation, the air outlet of the rack-mounted air conditioner 13 sends out cold air. The cold air circulates in the first cavity 23 and enters the space where the IT equipment 12 is located through multiple first openings 111, which facilitates the rapid cooling of the IT equipment 12 by the cold air. After absorbing the heat from the IT equipment 12, the cold air becomes hot air. The hot air is discharged from the cabinet 11 through multiple second openings 112, which facilitates air circulation.
